Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure node connector. Background Art

[0002] Steel structures are structures made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses made from sections and plates. They utilize rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for the construction of large-span, ultra-high, and ultra-heavy buildings. The material exhibits excellent homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. The material also exhibits excellent plasticity and toughness, allowing for significant deformation and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization allows for highly mechanized, specialized production.

[0003] H-shaped steel is an economical and efficient profile. Since all parts of the H-shaped steel are arranged at right angles, it has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight. It has been widely used in the construction of steel structures.

[0004] At present, most connections of steel structure nodes use multiple flat steel plates to connect two H-shaped steel webs and flanges respectively. However, the flat steel plates connecting the webs are separate from the flat steel plates connecting the flanges, that is, there is a connecting plate on each side of the web and a connecting plate on each of the upper and lower flanges. The connection strength is not strong and stable enough. Utility Model Content

[0049] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0050] See also Figures 1 to 7 As shown, the utility model provides a steel structure node connector, including:

[0051] A column 100 with an H-shaped steel beam 110 provided thereon;

[0052] A first inner connecting plate 200;

[0056] Among them, the first inner connecting plate 200 is provided with a first connecting block 210, and the second inner connecting plate 300 is provided with a second connecting block 310; when connected, the first connecting block 210 and the second connecting block 310 are fitted together and located between the ends of the H-shaped steel beam 110 and the H-shaped steel 600, and their upper and lower end surfaces are respectively used to connect the first outer connecting plate 400 and the second outer connecting plate 500.

[0057] Specifically, the first connecting block 210 is located in the middle of the first inner connecting plate 200, and the second connecting block 310 is located in the middle of the second inner connecting plate 300. Threaded holes 211 are defined on the upper and lower end surfaces of both the first and second connecting blocks 210 and 310. Through holes 410 corresponding to the threaded holes 211 are defined on the first and second outer connecting plates 400 and 500, respectively. The first and second outer connecting plates 400 and 500 are each threadedly connected to the threaded holes 211 via screws passing through the through holes 410. In this embodiment, the through holes 410 are waist-shaped, which facilitates adjustment of the positions of the first and second outer connecting plates 400 and 500.

[0058] Both sides of the first connecting block 210 and the second connecting block 310 are connected to a groove plate 220, and a plurality of first connecting holes 221 are opened inside the groove plate 220. The web of the H-shaped steel beam 110 and the web of the H-shaped steel 600 are opened with holes corresponding to the first connecting holes 221; the first outer connecting plate 400 and the second outer connecting plate 500 are opened with a plurality of third connecting holes 420, and the upper and lower flange plates of the H-shaped steel beam 110 and the upper and lower flange plates of the H-shaped steel 600 are opened with holes corresponding to the third connecting holes 420.

[0059] When installing, see Figure 2 As shown, in the first step, the first inner connecting plate 200 is placed on one side of the web of the H-shaped steel beam 110 and the web of the H-shaped steel 600, and the second inner connecting plate 300 is placed on the other side of the web of the H-shaped steel beam 110 and the web of the H-shaped steel 600, so that the trough plate 220 is attached to the web of the H-shaped steel beam 110 and the web of the H-shaped steel 600 and clamped, and then they are connected in sequence by bolts; in the second step, the first outer connecting plate 400 is attached to the upper flange plate of the H-shaped steel beam 110 and the H-shaped steel 600 and connected with bolts, and the second outer connecting plate 500 is attached to the lower flange plate of the H-shaped steel beam 110 and the H-shaped steel 600 and connected with bolts; in the third step, screws are passed through the through holes 410 and threadedly connected with the threaded holes 211 to respectively realize the connection between the first outer connecting plate 400, the second outer connecting plate 500 and the first connecting block 210, and the second connecting block 310. That is, the first inner connecting plate 200, the second inner connecting plate 300 and the first outer connecting plate 400, the second outer connecting plate 500 are respectively connected to the web and flange plates of the H-shaped steel beam 110 and the H-shaped steel 600, and then connected to each other into a whole through the first connecting block 210 and the second connecting block 310, with high strength, firm and stable connection.

[0060] See also Figure 4 and Figure 5 As shown, multiple second connection holes 222 corresponding to the third connection holes 420 are formed on both sides of the channel plate 220. This means that bolts can be passed through the second and third connection holes 222 and 420, respectively, through the first and second outer connection plates 400 and 500 to clamp the flanges of the H-beam 110 and H-beam 600, further enhancing the connection strength. In this embodiment, both the first and second connection holes 221 and 222 are waist-shaped holes, and their lengths are perpendicular. This allows the first and second inner connection plates 200 and 300 to be adjusted from two directions during connection, reducing connection errors and ensuring the reliability of the connection between the H-beam 110 and H-beam 600.

[0061] The first connecting block 210 and the second connecting block 310 are provided with a first guide rod 212 and a first guide hole 311 on their opposing surfaces, respectively. When the first connecting block 210 and the second connecting block 310 are abutted together, the first guide rod 212 can be inserted into the first guide hole 311. This means that the first guide rod 212 and the first guide hole 311 engage with each other to horizontally position the first inner connecting plate 200 and the second inner connecting plate 300, thereby improving the reliability of the connection between the H-beam 110 and the H-beam 600.

[0062] In order to further strengthen the connection strength between the first outer connecting plate 400, the second outer connecting plate 500 and the first inner connecting plate 200, the second inner connecting plate 300, a pair of dovetail grooves 213 are provided on the opposite surfaces of the first connecting block 210 and the second connecting block 310, and the dovetail grooves 213 are respectively located on both sides of the first guide rod 212 and the first guide hole 311; a first dovetail tenon 430 is provided in the middle of the first outer connecting plate 400, and a second dovetail tenon 510 is provided in the middle of the second outer connecting plate 500; when the first connecting block 210 and the second connecting block 310 are fitted together, the dovetail grooves 213 are combined into a dovetail tenon, and the first dovetail tenon 430 and the second dovetail tenon 510 can be respectively inserted into the upper and lower ends of the dovetail tenon to form a mortise and tenon structure.

[0063] See also Figure 6 and Figure 7 As shown, the first dovetail tenon 430 and the second dovetail tenon 510 are provided with a second guide rod 431 and a second guide hole 511 at opposite ends thereof, respectively. When the first dovetail tenon 430 and the second dovetail tenon 510 are inserted into the upper and lower ends of the dovetail tenon, respectively, the second guide rod 431 can be inserted into the second guide hole 511. In other words, the second guide rod 431 and the second guide hole 511 engage and mate with each other, thereby vertically aligning the first outer connecting plate 400 and the second outer connecting plate 500, thereby further improving the reliability of the connection between the H-beam 110 and the H-beam 600.

[0064] See also Figure 1 and Figure 3 As shown, the column 100 is a hollow square column, and each side of the hollow square column is provided with an H-shaped steel beam 110. That is, the H-shaped steel beams 110 on all four sides can be connected to an H-shaped steel 600, thereby completing the connection structure of the steel structure node.

[0065] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention.
